Nope! The first digit is the year and the following three digits are the days of the year. You have to know the decade, so starting with the 9, it could be 79, 89, 99, 09 or 19. So, you have to kinda know about when things happened in the evolution of the product to know the date. Since it is an old frame with the underlug barrel, no MIM hammer and trigger i would say the 289th day of 1989. whatever date that was.
